The future of batteries?

Supercapacitors have been around for a while and there have been a few companies promoting their future a a possible source of power for cars but they have not materialised commercially as yet. There has to be a reason for this - I suspect there could be safety issues, Lipos are no where near as volatile as this type of device.

Thé best will be organic batterie look at it take 30 sec to charge exist since 2000

Yeah we use supercapacitors in our motor controllers for the film industry, to keep the chip alive so it can keep a clock running whilst the unit is unplugged. It can keep the system alive for a few days.

Will be interesting to see where they go from here with it though....

When your using a super capacitor like a battery, as in charging it up and then discharging it over a long period, I wonder what differentiates it from a battery... There must be some technical reason why a battery is a battery and a capacitor is a capacitor...

Batteries produce current via a chemical reaction whereas capacitors store charge.

I suspect there is a bit more to it than that though.
